COMBINATION-LOCK.

SPECIFICATION forming' pant f Letters Patent No. 594,447, dated. November 30, 1897.

Application filed July 1'7, 1893. Serial No. 480,752. (No model.)

`coin-operated apparatus.

The object of the invention is to provide a combination-lock which will be simple, cheap of construction, positive of operation, -and free from tampering and which can be opened lock or catch of the apparatus to which it isv elevation.

only by one understanding the combination.

I-leretofore many and various combinationlocks have been produced in which all the moving -parts of the mechanism have been controlled by one knob and in which bolts or bars forming part of such lock have been actuated and thrown by the mechanism of the In my invention, however, the function of the lock is to conceal and shelter the connected, which catch or lock is ordinarily of a simple character, easily opened, and havingnoinherentsecurity. Myinvention therefore is in eiiect la guard or safety device for the locks or catches of any kind of apparatus or mechanism, and by reason of its shape and structure is practicallya safety-plug for locks and latches', which upon being removed exposes to view the fastening device of the apparatus in connection with which it is used.

To attain the above ends, I have constructed the device and combination of parts as hereinafter described and claimed, and illustrated in the accompanying drawings, in Which- Figure 1 is a plan of a bureau-drawer, for example, having in position'thereon over the ordinary lock the casing orV frame of my device ready to receive the removablev lock. Fig. 2 is a side elevation of the removable lock. Fig. 3 is a vertical section taken on the line a: of Fig. 4, showing one of the bolts in Fig. 4 is a plan similar to that of Figl, but showing the lock of Fig. 2 in place.

Fig. 5 is a transverse section taken on the line or otherwise secured to the casing A, pro-y vided with bolts 2, screw-threaded at the inner ends and having nuts 3 screwed thereon.

The casing is provided with two sets of lugs a a. and a' a', which are disposed at diametrically opposite points' and in pairs, the lugs of each pair being one above the other, as shown in Fig. 3.

The lock comprises three bolts B, C, and D, nesting one within the other, the outer one B forming a covering or cap b, which overlaps the edge and rests upon the upper surface of the casing A, to which it is removably secured by the dowels 4, entering sockets 5, and by which means said bolt is held from rotation. H The bolt B is also provided with two short circumferential slots b b2, arranged in different planes and on opposite sides thereof. At the outer end the bolt B is provided with a countersink or ange'b, in which rests the flange c at the outer end of bolt @,which latter is also provided at its inner end with a pinion c,which is operated through slot b2 of bolt B. The bolt C extends onlyto the inner wall of slot b2 and at its outer end is'overlapped by the flange cl at the outer end of the bolt D, which latter extends through bolts C and B and has its inner end iianged at d', so as to support and retain the other bolts B and C. Near its inner' end and beyond the inner end of bolt C the bolt D is provided with a pinion d2, which is operated through slot b' in bolt B. Surrounding the bolt B below its cap b are two rings or circular plates E E', each provided with a flange, the one e on ring E extending inwardly and the one e' on ring E extending outwardly. Each of said anges e e is provided with internal cogs or teeth e2. On the bolt B are suitably supported two IOO plates F F', of any suitable shape, having at opposite points shafts ff, carrying pinions f2 f3, the onef2 gearing with the pinion c on the bolt C and also with the teeth or cogs of the ring E and the other, f3, gearing with the pinion d2 of the bolt D and with the t-eeth or cogs of the ring E. rlhe ring E is also provided with notches e3 and the ring E' with notches e4, which are let into the liangcs c e', respectively, of said rings and are so arranged as to enable said rings to pass the lugs or projections a a. to permit the withdrawal of the lock. The flanges c d of the bolts C D are provided with beveled surfaces and with milled flanges c5 d", respectively. The bolt B is also provided with a beveled flange b". On the several beveled surfaces of bolts B, C, and D numbers, figures, scales, the., are placed. Each of the rings E E is also provided with a spring-actuated detent E2, the spring thereof normally pressing said detent toward the outside of the ring in the direction of the frame A.

As shown in Fig. G, the shaft G of the detent is squared or made angular in cross-section, so as to fit corresponding sockets (3n in the surface of the rings E E', (see Fig. 5,) and the detent 7 is swiveled to the upper end of said shank 6, which is rounded, so as to allow of the swivel movement of the detent under the control of the spring S. The sockets G are 'arranged at varying distances apart, and the arrangement of the detent in the different socket-s will effect a different combination for opening the lock, and the knowledge ot the position of such detent would give the key to the combination and enable the lock to be opened. The arrangement of the sockets C" is in accordance with a given scale, which is made to correspond operatively with the scale of the several bolts.

The operation of the device thus described is as follows: The parts reach the position shown in Fig. 5 by passing the notches c3 cAL of the respective rings E E over the lugs or projections cl. a of the casing A and then rotating said rings to prevent withdrawal thereof. It will be understood that the part or casing A is secured to some article, device, or apparatus having a mere latch or common lock to secure it closed, which may be represented at Z, and that the object of this invention is to protect or cover such lock or latch by being disposed in the manner shown and described. Now in order to get at the lock or latch fastening the device it is necessary to cause the notches in the rings to register with the lugs on the casing, so as to pull the combination-lock bythe lugs and thus expose the lock or fastening. To accomplish this, the bolts C and D are rotated from position where detent E2 rests against one of the lugs on casing A to cause predetermined numbers, ttc., constituting the combination on the three bolts to register with each other. The rotation of the bolts C and D causes the rotation of the pinions f2 f3, which in turn rotate the rings E E',

and when the combination has been properly manipulated the notches cg e will register with the lugs a a', thus enabling the removai of the lock. The arrow Z, Fig. 5, indicates the proper direction of rotation of the rings, and a reverse movement will render futile any attempt to operate the lock because of the action of the spring-detent upon the lugs of the casing.

Manifestly many changes in the details of construction can be made without departing from the spirit of' my invention-as, for example, one of the plates F F could be dispensed with, it being only necessary to firmly hold the shafts of the pinionsfzj?. Nor is it necessary that the inner ones of the pairs of lugs a a be present, as the outer ring will prevent the inner one being withdrawn.

Having thus described my invention, what I claim, and desire to secure by Let-ters latent, is

l. A masking device for locks and latches, consisting of a stationary casing and a withdrawable core; said core consisting ot' a ccntral operating-bolt projecting from the casing and rotating bolts arranged circumferentially with 'respect to said operating-bolt and operatively connected with rotatable rings adapted to register with retaining-lugs upon said stationary casing; substantially as and for the purposes described.
